Implement `TypeEngine.as_generic`
Added :meth:`_types.TypeEngine.as_generic` to map dialect-specific types,
such as :class:`sqlalchemy.dialects.mysql.INTEGER`, with the "best match"
generic SQLAlchemy type, in this case :class:`_types.Integer`. Pull
request courtesy Andrew Hannigan.
Abstract away how we check for "overridden methods" so it is more
clear what the intent is and that the methodology can be
independently tested.
